Bourns CSM2F series high power current sense resistors

Bourns is pleased to announce the introduction of its latest current sense resistor family, the Model CSM2F Series which includes CSM2F-8518, CSM2F-7036, and CSM2F-6918 models. This is Bourns’ range of high powered current sense resistors, manufactured using a metal alloy
element that is electron-beam welded to tinned copper terminals.
The Bourns® Model CSM2F Series comes in three different footprint sizes: 8518, 7036, and 6918 Metric, with resistance values as low as 50 µΩ, continuous current up to 1000A and permanent power ratings of up to 50W. The new Model CSM2F series is AEC-Q200 compliant with a high pulse power rating.
Their metal alloy current sensing element allows thermal EMF as low as 0.25 µV/K and low TCRs of 50 PPM/°C in the 20°C to 60°C temperature range.
Current sense resistors are growing in popularity due to their high measurement accuracy and relatively low cost compared to other technologies. These resistors detect and convert current to an easily measured voltage which is proportional to the current through the device.
